PROBLEM TO BE SOLVED: To provide an optical vibration detecting system utilizable, for example, even under a high-temperature environment, without having a vibration detection section affected by the external environment. SOLUTION: The optical vibration measurement system includes a vibration detecting section 110, that is connected to one end of an optical fiber 2 connected to a light source 210 for outputting physical measurement light, changes the intensity of the input physical measurement light according to disturbance vibration, and returns the physical measurement light to the optical fiber as return light; and the optical vibration measurement system detects information regarding the disturbance vibration, from intensity of the returning light of the vibration detection section 110.
